Simplee, which bills itself as "the Mint.com of healthcare expenses," launched in beta in late May and became available to everyone in June.

Simplee is a free Web app that lets users track and pay all their medical bills from one website. Patients can instantly see how much they are spending on healthcare, including what they pay versus what their insurance company pays, says CEO Tomer Shoval, one of three founders. A family's healthcare spending data is aggregated into one user-friendly dashboard, with information broken down by family member. The company's revenue comes from employers, brokers, HSA administrators and other corporate entities that sign up for its service, although it isn't yet profitable.

Users receive an email notifying them the minute a doctor's bill has been processed and can scan an explanation of benefits rewritten from their statement, only in lay language. Based in Palo Alto, Calif., the company has 15 employees and has raised $1.8 million from investors.
